A cylindrical blue glass continual release intraruminal device approximately 82mm x 24mm and weighing approximately 100g.
Each bolus contains the following active substances:
Copper: 13.4g Cobalt: 0.5g Selenium: 0.15g Iodine: 1.0g
Dosage and administration
Ruminating cattle over two months of age and weighing over 100 kg body weight: 2 boluses.
Administer orally using a balling-gun which delivers the bolus directly into the top of the gullet. Great care should be taken not to cause any injury by rough handling or by placing the gun too far inside the throat of the animal. Ensure that each animal has swallowed the boluses by holding the mouth closed and observing the animal for a short time. Gentle massage of the throat may facilitate swallowing of the boluses. To minimise the risk of regurgitation, avoid rough handling of animals. Administer every 4 months, or every 6 months to cattle at pasture.
The boluses can be given at any time, e.g. to dairy cows at drying off or at calving or 30 days
post-calving or at artificial insemination.
Boluses are sensitive to sudden temperature changes such as may occur when very cold boluses are swallowed by an animal. It is important that the bolus is at room temperature
(15 – 20°C) prior to administration. In the event of suspected overdose, see carton.
